A built-in gas fireplace is sized by the manufacturer’s framing (rough opening) spec — you’ll find the exact dimensions for this model in the Specifications tab above.

• New installs (direct-vent & vent-free) — confirm your wall or chase has the width, height, and depth the framing spec calls for, and plan the vent route for direct-vent models (through an exterior wall or the roof). Vent-free models need no vent at all.
• Inserts — measure your existing firebox in four places: front width, rear width, height, and depth, plus your chimney height. Compare against the insert’s minimum opening in Specifications.
• See-through & corner models — check the required wall depth between finished faces on both sides.

Buying online and hiring a local installer is standard practice — the manufacturer’s warranty applies in full. Line up your installer before you order: send them this model’s spec sheet, agree the venting route, then add the exact venting and accessories they specify in the configurator so everything arrives together.

Typical professional installation runs $800–$2,000 for inserts and simple direct-vent runs, up to $3,500+ for complex venting (labor and permits vary by region). Vent-free models with an existing gas line run less.

Free freight shipping within the contiguous US (Alaska, Hawaii, and Canada by quote). Fireplaces ship factory-new via FedEx, UPS, or AIT freight — you’ll receive tracking by email, and for freight deliveries the carrier calls ahead to schedule. Typical transit is 3–6 business days once shipped.

At delivery: inspect before you sign. Note any damage on the delivery receipt and contact us within 24 hours with photos — confirmed transit damage is repaired or replaced at no cost to you. Full walkthrough: how freight delivery works.

Returns: fireplaces and their configured accessories (log sets, liners, venting) are ordered from the manufacturer to your specification. You can change or cancel within 48 hours of ordering; after shipment, returns are handled with the manufacturer case by case — contact us first and we’ll make it right. Full details in our refund policy.

Every fireplace we sell is factory-new from an authorized dealer and covered by the manufacturer’s warranty. Napoleon warrants key components like the firebox and heat exchanger for extended periods — many with limited lifetime coverage on the combustion chamber — with shorter terms on burners, glass, electronics, and finishes (see the owner’s manual for this model’s exact schedule).

Keep your order confirmation as proof of purchase and register your unit with the manufacturer after installation. Need help with a claim? Contact us — we’ll coordinate with the manufacturer for you.
